[Press Release] Reduction in cloud condensation nuclei activity of water-soluble aerosols caused by biogenic emissions in a cool-temperate forest

Biogenic organic aerosols can affect cloud condensation nuclei properties. Researchers, however, are not yet sure of how the difference in the types of terrestrial biogenic sources and the abundance of organics relative to sulfate affect cloud condensation nuclei properties. A research group that includes Astrid Müller, a doctoral student, Assist. Prof. Yuzo Miyazaki (Division of Earth System Science), and Prof. Tsutomu Hiura (Division of Biosphere Science) have investigated water-soluble aerosols for two years in a cool-temperature forest at Tomakomai Experimental Forest, HU (northern Japan). They found evidence that a reduction in cloud condensation nuclei activity of water-soluble aerosols was caused by biogenic emissions from litter/soil microbial activity near the forest floor.
